Title: Method for manufacturing tape carrier package
Inventor: SASAKI SHINOBU
IPC: H01L21/60
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To prevent interlayer separation due to gas by a method wherein gas generated in sealing escapes from a device hole through degassing means. SOLUTION: A small hole 14 as degassing means is opened in a base film 1 near four corners of a device hole 2, simultaneously with punching of the device hole 2, etc. When sealing resin 7 is dropped, an IC chip 6 is sealed in the device hole 2 by controlling a position and quantity so that these small holes 14 are not buried with sealin resin 7. Thereby, as gas generated from the sealing resin 7 escapes from the small holes 14, gas is not sealed in the device hole 2. Accordingly, gas generated by sealing a semiconductor element with sealing resin or adhering a stiffener or a back plate with an adhesive sheet is closed in an airtight space, and it is possible to prevent an interlayer separation due to the gas.

Title: Current differential protective relaying device
Inventor: WATANABE KAORU
IPC: H02H3/28
Filed: 1988-09-28
Abstract: PURPOSE:To preferentially short-circuit effectively even in case of accidents of two or more phases in which the operation of an own terminal insufficient voltage relay cannot be expected by receiving the operating condition of an opponent terminal insufficient voltage relay, and generally judging the responses of the own terminal insufficient voltage relay and the opponent terminal insufficient voltage relay. CONSTITUTION:An own terminal preferential short-circuit is employed under the condition that accidents of one or more phases are detected from the elements of own terminal short-circuit insufficient voltage relay 6 and opponent terminal short-circuit insufficient voltage relay 21. Accordingly, if the relay 21 is operated, OR logics 11b, 11a attains '1' level, and the output of NOT logic 12 attains '0' level. Thus, the output of AND logic 13 is locked. Even in case of an incorrect response of a ground-fault current differential relay 5a, unnecessary tripping can be effectively stopped. Thus, a preferential short- circuit can be employed even in case of an accident in which the relay 6 cannot be operated by the operation of the relay 21.

The control voltage is a shift between the center frequency of the VCO 4 and the frequency of the oscillator 5, the shift is converted into a digital value by an A/D converter 8 and stored in a D FF 9. When the sampling period is stared, the switch SW 2 is thrown to the position shown in dotted lines, an interlocked switch SW 2-1 is closed, the control voltage stored in the D FF 9 is converted into an analog voltage by a D/A converter 11 and added to the control voltage by an adder 7.

Next, when a prescribed time is elapsed to reach the stop timing of the right pattern, the right pattern is temporarily stopped similarly. When the right and left patterns are identical, REACH is generated.  When REACH is generated, a decoration display such as images or characters with a story are displayed in the back ground area of a REACH variable display and patterns and the patterns are temporarily stopped at a prescribed pattern and then a variable display is carried out again and then the determined stop is carried out.
